Dr. Tyson G. Harmon

Assistant Professor, Department of Communication Disorders
I am interested in research that advances behavioral assessment and treatment of adult neurological communication disorders. Specifically, I am interested in understanding how language functioning and recovery after stroke is affected by mood and attention and in learning how to help people with aphasia transfer gains made in therapy to their everyday communication.

I am from Modesto, California and I love to wakeboard, try new foods, bake, and spend time with my family and friends. I am a Senior here at BYU studying Communication Disorders with a minor in Gerontology. I recently married my best friend Levi in April and have never been happier! I love this field and the potential we have to help patients of all ages achieve the quality of life they desire. When I first started this major, the effects of aphasia and TBI on a patient’s ability to communicate quickly fascinated me, so I am beyond excited to already be involved firsthand in this facet of the field.
